CAN-HEADING MACHINE.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed Uctober 19,1905. Serial No. 283,367.'

To ctZZ whom, it may concern:

Beit known that I, JULrUs BRENZINGER, a citizen of the United States, residing at Mount Vernon,Westchester county, State of lNew York, nave invented new and useful- Improvements in Can-Heading Machines, of which the following is a specification.

This invention relates to a machine for forming the seam or joint between a (ianbody and its superposed head.

The machine is vso constructed that the seaming means are advanced against the work 1n a sim-ple, novel, and very efficient manner.

In vtheaccompanying drawings, Figure 1 is a front elevation of my improved can-heading machine; Fig. 2, a right-hand side view thereof; Fig 3, a left-hand side view of part o fthe same; 4, a horizontal section onl Ihne 4 4, Fig. ZFig. 5, a similar section online 5 5, 2, with some of the parts omitmachine-head, Fig. l1, a side view, partly in section thereof. with the chuck omitted; Fig. 11a,- a cross-section, partly broken away, on line 1a 11a, Fig. 11; and Fig. 12, a vertical section online 12 12,-Fig. 10.

The letter a indicates a normally stationary table or su port upon which thecans to be closed are adapted to be placed.4 Table a isfrmounted on a vertically-adjustable support b, flanged to engage rails A of the machine-frame A. Through a central. opening of table af passes a vertical shaft c, stepped iny bearings b b2 of supp ort b. This shaft carries at a slight distance above table a a horizontal feed-disk D, that conveys the cans to be' closed to the seaming means. The disk D.is composed of a circular plate d, fast on shaft-'c and provided with a'series of radial grooves d. Within the latter are slidably tted the Shanks d2 of a series of radiallyfadjustable forks or can-holders d3,which may be locked to plate d by clamp-screws d4. A curved peripheral guard a/ of table a coperg. 7, va detail front viewof the rack.

ates with forks d3 to insure a proper presentation 'of the cans to the'seaming means hereinafter described. v

Feed-disk D receives intermittent rotatory motion in the4 followingmanner: To frame .A is journaled a power-shaft e, which transmits motinvby pulley e and belt e2 toa p'ulleyf. The latter constitutes part ofthe head F .for operating theseaming-rollers and turns on a'vertical-stationary shaft f, mountf ed in frame A. To hub]02 of pulley f is se-` cured a pinion f3, that engages a gear-Wheel .g, fast-on a vertical shaft g. Shaft g is rotatably mounted in a bearing of lframe A andcarries at its 'upper end a' pi'nion'g, engaging a gear-wheel fast on a vertical shaft h. The latter ismounted in an upper bearing A3 offrame Aand in a pair of lower bearings?)3 b4 of support 5. 'To shaft' k is secured by 'groove-and'feather connection a. gearv wheel 71,2, engaging agear-Wheeli of like A(lia'meter and pivoted to support b. To wheel 'i is fulcrurned 4'at t' one en of a link 21,2, the other endof which is pvot'ed 'at 5,3 to,a lever t4, loosely mounted on -shaft c.' To.- the free end of lever itis pivoted a spring-influenced pawl '215, adapted to engage a ratchet-wheel-c,

fast on shaft c.l The number of' teethf ratchet-wheel c is equal to the-number of forks da. It will thus be seenthat at each completerotation' of shaft h wheel 'i will also make acomplete rotation to advance ratchetwheel cf for the length of one'tooth.. This partial rotation of ratchet-wheel c will rotate forks d3 for a space equal tothe distance between the centers of two adjoining forks. In this Way a new can will be presented to the seaming means, hereinafte`rdescribed, at each complete rotation of Vshaft It.

After a can has arrived below the seeming means it is raised into engagement with the same in the following manner: Table .ais provided with a circular openingc2., the center of which is vertically below the center of the seaming means. Opening a2 is adapted to inclose an alined vertically-movable plat- Platform j may be reciprocated so `as to bring the cans into or out of operative engat-gement with the seaming means in the f ollowing manner: To'hub of wheel 712 is 'conne'cted a bevel-wheel h3, that engages a bevelwheel Zr of like diameter. 'Vheel c/ is fast on a horizontal shaft Zr, turning in bearings b5 b of support b. Shaft Zr is provide-d with a cam ZC?, which is engaged by a roller Z of a lever composed of two parallel arms Z Z, that turn, on a fulcrum Z of support Z), Fig. 8. Arms Z Z are connected by a transverse rod Z2, upon which the vroller Z is rotatably mounted. .The free ends ofarms Z are connected by links Z3 to a collar j', loosely mounted upon a rod jl, that carries platform Upon collar j are supported a pairxof cushions j, that bear against a collar y, fast on rod j?. It will be seen that if the larger section of cam Ze? engages roller Z platform will beraised, while when roller Z is engaged by the reduced section of cam k2 tylieplatform will be lowered.

In order to positively lock feed-disk D while the seaming operation takes place-i, e., while pawl ifi recedes from one tooth to engage the succeeding tooth of ratchet-wheel c/ shaft ZC is provided with a second cam 153, which is engaged by a roller m/ of a lever m, pivoted to support Z3 at m2. The free forked end of lever 'm embraces a boltn beneath a collar n@ fast on said bolt. The latter tically slidable in bearings bs bH of support 0 and is normally retracted by a spring n?. The boltv n engageswhen raised one "of a'series of perforations di of pla-te d, so, that while this engagementv takes place feed-disk D is looked against rotation.

In order to instantaneously arrest the feeddisk and prevent its rotation by momentum after pawl if has completed its forward stroke, a brake cembracing shaft c, may be provided.

rThe seaniingT means hereinabove referred to consist. of two pair of seaining-rollers, the roilers of each pair beine' placed dialnetrically opposite each other.V Means are provided for so actuating' the rollers that while the lirst pair is advanced to opera-tiveiy engag-e the can-body the second pair ret roth and vice versa. The tirst pair of rollers is profiled to form al lap-joint between cairbody and. can-head, while the second pair is profiled to cninpress said. joint into a ilat air-tight seam, a usual. The means for operating each pair of rollers are identical andare as follows: rEhe seeming-rollers o turn on upright axles o of riulially-movable slides Q.' adapted to rotate with head F around the can-liody. The slidr are .fuf-tuated by stationary worin f* ci shaft j and around which the head F turns. This worin is engaged by worm-wl'ieels p, there beii'ig one' wormovheel for each slide O. Each worm-wheel p is fast on a horizontal axle p, rotatabie in bearings i f 1 j oi head t.

clamp-screws 0*. '.:ofwrollers o, ball-bearings 01 niav be inter- To accommodate worm-wheels p, the hubf3 is'slotted. as atf. Each wormwheel'p is provided at each side with a. fixed cam p2, such cams beingengaged by apair of rollers 1", pivoted tothe forked end 1' of a. lever r. Each lever r ispivoted at r3, to a support r4, secured to the bottom plate f7 of head F. Lever r is provided with a downwardly-extending` tailpiece r, which is received by a corresponding perforation 03 of an upper section o" of slide O. The slides O are guided in radial groovesf of a downward extension f 9 of head F. In order lto adapt the machine to cans of different diam ters, each slide O has a lower section 05, ra ially movable with relation to the upper section 0*. Section o4 is provided with a radial guideway o, within which section 0 is slidable. An adjusting-screw o7, turning in bearings 08 of section 0*, is received by an opening between parts 04 o5 and 'engages a lthread cut intov partl 05, while it can rotate freely inthe upper part of the opening formed in part 04. Thus by manipulating screw o7 the lower part 0'", which carries theV sean'iing-roller 0, may be moved radially inward or outward, so as to adapt' the machine to can-bodies of different sizes. After the section o5 has been properly adjusted it is locked in position by To insure afready rotation posed between the upper surface of such rollers and the section o".

It will be readily understood that the rotation of head F and the corresponding revolution f worm-wheels p around fixed worm f* will .result in a slow axial rotation of such wheels owing to theirengagement' with the worm. Vheels p will thus rotate cams QJ?, and when the enlarged sections of such cams engage roilers r levers r will be tilted to force the slides O inward and bring the an'ungrollers o into operative contact with the canhead7 so as to forni the seam. The cams p2 of the two pairs of scathing-rollers o are so set that while one pair is advanced the other pair retracted, as will be readily understood. To the lower end of fined shaft fis secured a fixed chuck s, which is adapted to enter a cen tral depr ion T2 of lani-head T, se asvto hold the can-body T and cover T in proper position while the seaining operation performed, i? Q. v

in order to insure a ready and positive diseiigaseinr-:nt of the aus from the chuck after the former have been closed, sl aft fis made tulular and conmninicates at its upper end h a pipe u, which may be connected. to a tank or other suitable means (not shown) for containingy a pressure medium, such as cornpresserE i ipe yu is provided 'with a cock u, which is operated by a spring-infinenced lever u?, carryingr a roller 1.63. This roller is adapted to engage a can). Zit, connected to gearewneel ZL. d hen roller 'uz engagqsth/c IIO E lid raised section of cam h4, valve u( is opened, While when the roller clears such section the valve will be lclosed by the action of a spring a4. The parts are so assembled that valve u isopened upon the completion of the seaming operation and is closed before the next can-cover engages chuck s. e l

rlhe support b is vertically adjustable, as already stated, to adapt the machine to cans of different heights. For this pu ose there is secured to frame A a rack @,'w "ch is engaged by a pinion v', fast on a shaft 222, hav-I ing hand-wheel 'v3 and free to rotate inv abracket b1 of support b. The latter may be locked in position after it has been set by tightening a pair of clamp-screws@ passing through ,slots A4 of frame A and tapped into sup ort b. v

- T e machinev operates as follows: nHead F, together with shafts h and c, are continuously rotated by the means described. The. can-body T, with superposed head T, is placed upon table a, between-the shanks of oneof the forks d3.. By the intermittent rotation of fork da the can-body will be carried against ard a, which serves to center it Within t e-fork. When the can has thus been pushed by its fork upon platform j, the latter Will be raised to -bring head Tfiuto engagement With" chuck' s. The first and second` pair of seaming-rollers, Which revolve with the head F around the can, are now suecessively advancedto rst form a lap-joint betvveen the parts T and T and to then llatten said joint. After the seaming operation has .been completed platform j is lowered and the pressure medium is turned into tubul lai` shaft'f to forcibly disengage the can from the chuck. The can will now be pushed by 40 one of the forks from platform 'y' upon ta- `Wheels engaging the Worm, and means actu blea and along the latter until it is thrown oil the table by a suitable deiiector a3, with which the table is provided.
